      We are investigating the cause, but it is not clear yet.
      It seems that there's memory leak on active check process.

      + INFO (2017/07/04 add)

      The memory leak occurs when:

      • log[] or logrt[] item uses a global regexp consisting of several (at least 2) subexpressions,
      • the first subexpression checked is of type "Result is TRUE" and matches (exact match is TRUE),
      • the next subexpression checked is of type "Result is TRUE" or "Result is FALSE" (whatever TRUE/FALSE)

        There are no Sub-Tasks for this issue.
